Battle Princess Diana’s cancer battle was a private one, but she did share some of her experiences with the world. In a 1997 interview with BBC’s Panorama, the late royal opened up about her health struggles, including her cancer diagnosis.

The Princess of Wales made her first public appearance since announcing her breast cancer diagnosis in February. Princess Diana, who was 36 at the time, was diagnosed with the disease in 1993.
